Replacing windows
Replacing the windows in a Brampton house
If someone has called or knocked about a "window replacement program", it's right to ask questions. We aren't a government program and we don't knock on doors. We're a free referral service: tell us which windows you're considering, and we connect you with an independent local installer who measures, quotes in writing and does the work. Many Brampton homes only need new glass or parts, and the installer should say so. When frames are failing, replacement is the right call.
- Written, itemized quotes
- Plain answers on permits and rebates
- Planned around tenants and family
Time for new?
Signs the whole window is done
One alone may be fixable; see other window fixes. Several together point to replacement.
The frame is damaged
Cracked or warped vinyl, rot in a wood frame or sill, or water stains below after rain.
Fog is spreading through the house
One foggy window is a glass job; see foggy window repair. Fog in window after window, on top of other wear, starts to favour new windows.
It won't open, close or lock properly
When new hardware has already been tried, or parts are no longer made, the window itself is the problem.
Air leaks around the frame
Drafts around the outside edge of the frame, not just the sash, and cold spots along the wall in winter.
Two methods
Insert or full-frame replacement: what each involves in brick-veneer and vinyl-sided homes
The installer recommends one of two methods after looking at the frame, and each quote should say which it uses.
Insert replacement
The old sash and glass come out, the existing frame stays, and a new window fits inside it. Trim, brick and siding are left mostly alone. It suits square, dry frames and is the tidier install.
Full-frame replacement
The whole window comes out, down to the rough opening. The installer checks for water damage, sets the new frame level on shims and seals the gap with low-expansion foam. On brick-veneer homes the brick stays and new capping covers the edge; on vinyl-sided homes some siding comes off and goes back.
Permits
Permits in Brampton
Check before you change anything. In Churchville's heritage district, replacing windows needs a heritage permit, and the district plan asks for replacements that match in kind. Minor repairs don't need one. Elsewhere in the city, the rules below apply.
Same-size replacement
The City's list of work that doesn't need a permit doesn't mention windows either way. A permit is generally not required for same-size replacement; confirm with the Building Division before work starts. The no-permit list is the place to begin.
Enlarging an opening or adding a new one
A bigger opening or a new one needs a building permit. The City's new or enlarged openings package asks for a survey, elevation drawings and lintel details. It comes up most when a basement window is enlarged for a legal basement or second unit.
Condo townhouses
In a condo townhouse, windows are often part of the common elements. Talk to the condominium corporation first. Where a permit is needed for common-element work, the City asks for a Notice of Permission to Construct signed by the corporation.
Energy ratings
ENERGY STAR today: one national standard, no zones
Canada's ENERGY STAR specification for windows is one national standard, set by Natural Resources Canada. There are no climate zones any more, so a quote that talks about a "zone" is working from old information. A certified window meets a maximum U-factor or a minimum Energy Rating.
What to compare
Each quote should name the product's ENERGY STAR certification and its rated U-factor or Energy Rating: lower U-factor, less heat lost; higher Energy Rating, better. Compare frames on vinyl windows and styles on casement windows.
What to be wary of
Promises about exactly how much you'll save on heating are hard to back up. Rely on the certification and the rated numbers, not the pitch.
Rebates
Rebates in 2026: what's real and what's a pitch
Ontario's Home Renovation Savings program pays back a set amount per rough opening for ENERGY STAR certified windows and doors. For windows, you generally start with a home energy assessment and then complete two or more upgrades. Check the program site before signing anything. No federal window grant is open now, and the City has no window rebate of its own.
If heating bills are a real strain, Peel homeowners can look at the Centre for Community Energy Transformation's Energy Retrofit Assistance pilot. It can include select windows, offers language help and has limited places.
The "program" check
The real rebate starts with an energy assessment. Someone at the door offering a "window replacement program" is selling windows. Ontario's door-to-door restrictions don't cover windows, but a contract you sign at home generally comes with ten days to cancel.
What affects the quote
What drives the price
The usual reasons quotes differ:
- Number of openings, and whether they're done in one visit
- Window style: casement, awning, slider, picture or a combination
- Frame material and colour, inside and out
- Glass package: double or triple pane, low-E coating, argon
- Insert or full-frame installation
- Interior trim, exterior capping and caulking
- Permit work for any enlarged opening
Ask for each opening to be listed separately so quotes can be compared line by line.
Quotes and contracts
Your rights on the contract
Get every quote in writing. A good one lists each opening with its size, style and glass, the install method, trim and capping, removal of old windows, product and labour warranties, the payment schedule, and start and finish dates. Brampton's business licensing by-law expects licensed renovators to give a signed contract with an itemized price, warranties and a completion date, which is a fair standard to ask of anyone.
Under Ontario's consumer protection law, a contract signed in your home generally carries a ten-day cooling-off period. A contractor also can't charge much more than a written estimate unless you agree to the new price.
Install day
Install day in a two-unit house
Replacing windows means someone working in nearly every room. In a two-unit house, the tenant downstairs needs notice and a time to let the installer in, and it helps to agree which rooms go first. Ask how floors are protected and how dust and old glass are handled.
The installer who takes on your job should arrive when agreed, cover furniture, clean each room before moving on, and explain the work to whoever is home.

Tell us how many, which rooms and roughly when the house was built. We'll pass it to an independent local installer for a written, itemized quote. If new glass would do for some, they should say so.
